IMPROVEMENT IN APPARATUS FOR DYEING.

Specification forming part of Letters Patent No. 126,578, dated May 7,1872 antedated May 1, 1872.

SPECIFICATION.

I, GEORGE MICHAEL ROHRBACHER, of Philadelphia, county of Philadelphia,State of Pennsylvania, have invented certain Improvements in DyeingApparatus, of which the following is a specification:

Nature and Object of the Invention.

My invention consists of certain improvements in dyeing apparatus (toofully explained hereafter to need preliminary description) wherebyskeins or hanks of yarn maybe dyed much more rapidly and uniformly, andwith much less labor on the part of the attendants, than by the usualappliances.

Description of the Accompanying Drawing.

Figure 1 is a side elevation of my improved dyeing apparatus; Fig. 2, aplan view of the same; and Figs. 3 and 4, detached sectional views ofthe upper portion of the apparatus.

General Description.

A represents a dyers vat or tank of the kind commonly used for dyeingyarn in skeins or hanks.

To prevent tangling, and for convenience of manipulation, the skeins ofyarn are usually strung upon sticks, which are laid transversely acrossthe top of the vat, so that the suspended skeins may be steeped in thedye, with which the vessel is filled nearly to the top, and which iskept heated nearly or quite to the boiling-point by a coil of steampipesor otherwise. As only the lower portions of the skeins are submerged inthe dye it becomes necessary, after a suflicient time has elapsed tothoroughly impregnate these submerged portions, to turn or shift thewhole number of skeins upon their sticks, so that the upper portionsalso may be submitted to the action of the dye. My invention has beendesigned to facilitate these and other opera; tions.

The sticks B B B, &c., are each formed with journals (1 a adapted tohearings in the top of the Vat, and are provided with pinions b at oneor both ends, either geared directly together or to an under row ofgeared pinions, c, this arrangement enabling an attendant to turnsimultaneously the whole of the sticks or spindles from which the skeinsof yarn are suspended, such motion being either intermittent orcontinuous, as circumstances may suggest.

It will be seen that any one or all of the sticks may be lifted for thepurpose of removing the skeins; but I prefer to adapt all of the saidspindles to a frame, 0, Fig. 3, which fits within and rests upon ashoulder, h, formed within the vat, and which, with the spindles andskeins, can be lifted bodily from the vat and be removed to the placewhere the skeins are to be dried.

Claims.

1. The combination, substantially as herein described, of a dyers vatand a number of detachable sticks or spindles, B, provided with pinionsb gearing with each other or with a row of supplementary pinions, c, asset forth.

2. The detachable frame G, adapted to the top of the vat A, and carryingthe geared and detachable sticks or spindles B, all substantially asspecified.

In testimony whereof I have signed myname to this specification in thepresence of two subscribing witnesses.

G. M. ROHRBAGHER.
